MANUFACTURE OF THREE-DIMENSIONAL LAMINATE

摘要

Processes for forming a continuous thermoplastic laminate having a molded three-dimensional surface on a least one side thereof. Such laminates can be formed by fusion bonding a three-dimensional thermoplastic layer being formed by continuous injection molding on a rotating mold drum to a substrate layer, which can be a generally flat sheet or optionally a three-dimensional layer. As the mold drum rotates the laminate is cooled sufficiently to allow the three-dimensional structure to be extracted from the mold drum. In a preferred process a three-dimensional layer having grass-like elements extending from a substantially uniform backing with low residual stress is laminated to a substrate to form a spray-suppression device with improved low temperature break resistance.
